An aluminum IP30 enclosure, wide 7–57 VDC input and -40 to 75°C operating range keep links stable in harsh environments, while a non-blocking 8 Gbps fabric ensures full-speed traffic across all ports. Key Benefits & Features 4× GbE RJ45: Auto-MDI/MDIX 10/100/1000 Mbps ports for flexible copper uplinks and edge devices. Wire-speed switching: 8 Gbps non-blocking bandwidth with jumbo frame support up to 9216 bytes for efficient payloads. Industrial power options: 2-pin DC input (7–57 VDC or 9–40 VAC) with passive PoE power-in via ETH1 (Mode B, 9–30 VDC) for simplified installs. Hardened build: -40 to 75°C, IP30 aluminum housing, integrated DIN-rail bracket for fast, secure mounting. Standards & compliance: IEEE 802.3i/u/ab/x/az support with CE, FCC, UKCA and other certifications for global deployments. Ideal Use Cases Industrial automation panels and PLC networks needing compact GbE aggregation Transportation and building systems requiring extended-temperature switching Energy, utilities, and SCADA cabinets with DIN-rail power distribution IP cameras and sensors at the edge where unmanaged simplicity is preferred Technical Specifications Ports: 4× RJ45 10/100/1000 Mbps (auto MDI/MDIX) Switching capacity: 8 Gbps (non-blocking) Buffer / MAC: 128 KB packet buffer, 2K MAC entries Jumbo frames: Up to 9216 bytes Power input: 7–57 VDC or 9–40 VAC via 2-pin socket Passive PoE-in: ETH1, Mode B, 9–30 VDC Power draw: 0.26 W idle / 1.44 W max Operating range: -40 to 75°C; 5–95% RH non-condensing Enclosure & size: Aluminum, 102 × 25 × 81.5 mm; 210 g Mounting: Integrated DIN-rail; wall/flat mount with kit Deploy with Confidence Power-efficient, standards-compliant, and built for harsh sites, the TSW304 delivers reliable Gigabit switching in minutes.
